I would put it this way psychotropic. Most will not hear a difference between the Rethms and the Focals. I'm saying this because most have not even heard the Rethms itself forget the Focals. The Rethms themselves are out of the reach of most of our countrymen.
However, there will be a few who will hear the difference between the Rethms and the Focals and for such the Focals will justify all the expenses involved.
Perhaps you are using the Rethms and Focals as examples, but it would be unusual to find someone who will not hear/notice the difference between the Focals and the Rethms...not a question of better, but they are very different.
On another point it may come as a surprise to forum members but two of the speakers on this list are actually in Bangalore .... and guess what? ....
in the same house
